You've seen that effect even in modern times. Twenty years ago, a few idiots in control of the world's most populous nation were able to shut down the educational system for one billion people at the time of the Great Cultural Revolution, whereas it's impossible for a few idiots to shut down the educational system of all of Europe.

Does this mean that a high degree of fragmentation is even better? Probably not. India was geographically even more fragmented than Europe, but India was not technologically as innovative as Europe. And this suggests that there is an optimal intermediate degree of fragmentation, that a too-unified society is a disadvantage, and a too-fragmented society is also a disadvantage. Instead, innovation proceeds most rapidly in a society with some intermediate degree of fragmentation.
